Sean Finney discovered several insecure temporary file uses in toolchain-source, the GNU binutils and GCC source code and scripts. These bugs can lead a local attacker with minimal knowledge to trick the admin into overwriting arbitrary files via a symlink attack. The problems exist inside the Debian-specific tpkg-* scripts. For the stable distribution (woody) these problems have been fixed in version 3.0.4-1woody1. For the unstable distribution (sid) these problems have been fixed in version 3.4-5. We recommend that you upgrade your toolchain-source package.
